2. Use textbooks recommended by the government. If it's math, buy a math textbook; if it's not math, buy a non-math textbook. In the process of reading, I would rather read less than swallow dates. By doing some real questions in previous years, you can find the part that you are more confident to complete in the exam. In actual exams, people often get very low marks, and the most important thing is to get the marks they can get.
3. This part is mainly to expand their mathematical ability and enhance problem-solving thinking. Mathematical analysis is a course with many contents in the university, and there are many theorems in it. Therefore, it is important to learn mathematical analysis, such as expanding generalized Lobida's law from Lobida's law, mastering Stoertz's theorem to deal with the limit of sequence, and so on.
4. If you are a junior or above, you should also prepare the course of linear algebra for the exam preparation. The most important thing in linear algebra is to pay attention to the use of matrices. This piece still needs to improve itself by combining problems, and can't be satisfied with solving matrices, solving matrices and other operations.
